INK-SUPPLYING DEVICE.

Specification of Letters Patent.

latented (let. it 1915.

Application filed April 1, 1914. Serial No. 828,839.

To all whom it may concern:

lie it known that I, Monnie Bonsonr, a citizen of the United States of America, and a resident of New York, in the county and State of New York, have invented a certain new and useful Ink-Supplying Device, of which the following is a specification, the same being a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to viscous colored substances used in printing, and in particular to means for feeding ink to the elastic cylinders ordinarily known asinking rollers; to a container for the same constructed and arranged to preserve the ink without deterioration; to means for charging the said container; and to other novel devices and combinations of devices as hereinafter set forth, the whole forming in operation a simple and etlicient organization.

In order to enable the invention to be fully understood 1 shall. proceed to explain the same by reference to the drawings, illustrative of one practical embodii'nent of the invention, which accompany and form a part of this specification, and in which Figure 1 is a front elevation, partly in section of a machine constructed according to my invention, Fig. 2 is a side elevation, partly in section of the same; Figs. 3 and l are views in detail of parts of the container, and Fig. 5 is a view representing means to charge the container.

Like letters of reference indicate like parts in all the views.

Referring particularly by reference symbols or characters to the drawings, A denotes a preferably rigid supporting frame for my attachment to a printing press, preferably having means, as A, to adjust the height thereof relative to the ink distributing disk B of the press, upon which the reciprocatory inkingrollers C work. At the top of the said frame is preferably pivoted, as at a, a swinging frame D which may serve to support a shaft 0 and a gear F. Upon the shaft 6 is mounted a worm E and a ratchet wheel E, the said worm being constructed and arranged to engage the gear F, and the ratchet wheel being kept from backward rotation by the pawl Gr which is supported by the frame A and preferably has adjusting means, as a screw g, by which it is adapted to be raised or lowered so as to rotate the wheel the distance of one or more teeth at will when the swinging frame D is moved in an inward direction, the said pawl being shown in a raised relation by dotted lines in the drawings.

The gear F has a shoulder f which works in the relatively horizontal portion of the frame D and also a depending hollow shaft F. An ink container 1 is preferably made in cylindrical form with an eXteriorly threaded mouth or outlet i and an open top portion across which is preferably placed a cross bar H, which is prevented from rotation by a. stay (Z located intermediate the frame D and the bar H. Within the container works a piston K formed with an interiorly threaded orifice to engage the lower threaded portion 5 of the stem K", the upper part of the latter being extended upwardly so as to lie within the hollow shaft F and being secured in detachable relation to the latter by '1. pin By removing the pin j, the container may be taken away from the press either when the said vessel is empty, or when it is desired to change the color to be printed by the substitution of another container charged with a different colored ink.

A shoulder h and washer it serve to hold the stem K to the cross bar H, the said washer being prevented from working loose by the pin j.

The piston K preferably has packing placed around its periphery in order to constitute a'movable air tight joint or upper closure or cover for the container, and also to prevent any rotation of the same. It is also preferably made with a spring 7t" having a pin extending downward through the piston in orcer to serve as an indicating device when the same, in its downward movement, reaches a position adjacent to the bottom of the container by the said pin lifting the free end of the said spring upwardly so as to clearly and visibly denote when the said movable closure has reached its limit of downward movement.

An ink feeding pipe M is constructed so as to have a flat face at the lower part thereof, as shown in Fig. 4, in which face are formed perforations or feed orifices m, and at each side of the latter are laterally extending flanges or extensions M in order to present a larger bearing surface so that'the soft or elastic inking rollers shall not be unduly depressed or indented. The feed pipe M is detachably secured to the container 1 by a suitable device as by means of a union L. When temporarily out of use, the perforations m may be closed as by a closure N having wires 1?. to enter the said perforations. When, however, the container is not desired to be used for a comparatively long period of time, the pipe M may be detached and a lower closure as N may be screwed upon the mouth or outlet 2', as indicated in Fig. 3, so as to tightly seal the same, with or without removing the container from the frame D.

In operation, the inking rollers C move the feed pipe ofthe container mounted in the reciprocatingframe D in a forward or inward direction, thereby impacting the pawl and ratchet wheel E and causing the latter to advance with a slight rotation. This movement allows the worm E to cause the gear F to also revolve a little, and

through its hollow shaft F and stem K the movement is communicated to the piston K which is moved slightly downward, thus forcing a small predetermined quantity of ink out of the mouth or orifices of the feed pipe in order to supply the rollers. As the latter recede again in their reciprocatory action, the swinging frame will be free to move back again to its original position which is preferably accomplished by means of gravity alone, and in order that this movement may not be a too rapid one, the same may be checked as by the use of a dash pot P which is connected respectively with the frames A and D.

Occasions may arise where I may desire to supply a large quantity of ink at one time, and in such instances I may attach a crank e to the shaft 6, thereby operating the piston K manually instead of automatically as in the manner described.

My invention also provides a ready means for charging the containers with ink, as by making a relatively large charging container 0 of practically similar construction and attaching the same to the container used in the press so that the mouths or outlets of the two shall register with each other, the smaller Vessel being in an inverted position and having the piston at the mouth thereof, the said closure being adjusted in the said position by a rotation of the stem K opposite to that which occurs when the container is in use on the press. By now manipulating the crank O the ink from the charging vessel will be'forced into the smaller container in such quantity as may be desired.

It will be noted that the ink in the container is always kept free from deterioration as the same is in a continuously practically sealed condition, and as no air can reach the ink it will not become thickened or form a skin on the surface of the same. In the ink containers ordinarily used much ink is Wasted as when the vessels are once opened there is no means to prevent the oxidation of the contents of the same, and it often happens that where only a small quantity of ink-especia1ly an expensive colored inkis desired to be used, the remainder of the ink becomes worthless before it is needed on another job of the kind. With the employment of my container, however, no matter how small a quantity of ink is required for use, the vessel may be removed from the press and sealed up again, and also upon being required for use once more at a subsequent period, the container may be unsealed and applied again to the press, whereupon it will be found that the ink within the 0011- tainer is as fresh and good as when it was first used.

The employment of my invention is very economical as the feed supply can be regulated to a very fine degree, so that just the proper amount ofink can be supplied to the rollers to do the printing properly without any danger arising of waste on account of there being any ink in the container that cannot be utilized.

I wish it to be understood that I do not desire to be limited to the exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art.

l/Vhat I claim as my invention is 1. In a device of the class described, a container having an open mouth, a central spindle and means for holding the same to the container, a movable closure located below the said open mouth and operated by the said spindle, and means for rotating the said spindle, in combination with means for adjusting the degree of rotation of the said spindle.

2. In a device of the class described, a support having rotatable driving means, a container adapted to hold ink, a device located at the top of said container having fixed attaching means and also rotatable attaching means projecting therefrom, and means to secure the said rotatable attaching and driving means together and to detach the same at will, in combination with a movable closure within the container constructed and arranged to be operated by the said rotatable attaching means while the container itself is held from rotation by the fixed attaching means.

In testimony of the foregoing specification I do hereby sign the same in the city of New York, county and State of New York this 12th day of March, 1914.
